IMPROVEMENT IN LAMP-HEATERS.

Specification forming part of Letters Patent No. 139,140, dated May 20,1873; application filed March 13, 1872.

To all whom it` may concern:

Be it known that I, WILLIAM FRIEL, of San Francisco, San Franciscocounty, State of Calitornia, have invented an Improved Vapor-Burner forHeating; and I do hereby declare the following description andaccompanying drawing are sufficient to enable any person skilled in theart or science to which it most nearly appertains to make and use mysaid invention or improvement without further invention or experiment.

My invention relates more particularly to that class of vapor-burnerswhich are used in the ordinary gasoline cook-stoves for the purpose ofproducing heat for cooking purposes. My improvement consists in theemployment of a peculiar dish, which is fixed to the generatorjust belowthe openings through which the vapor or gas escapes to be burned, andwhich serves, by spreading the flame, to produce great heat, suitablefor cooking or other purposes.

In order to explain my invention, reference is had to the accompanyingdrawing forming a part of this specification, in which- Figure 1 is anelevation.

In order to properly explain my invention I have connected it with anordinary fountain, such as is used in burning gasoline and other lighthydrocarbons in order to give the required pressure.

A represents the fountain, which is placed at the upper end of thevertical tube B, land C is a branch pipe which connects with the pipe bto lead the hydrocarbon-oil to the generator D. This generator is filledwith a fibrous material in the ordinary way, and is provided with one ormore small holes a short distance below the upper closed end, throughwhich the vapor escapes to be burned.

Thus far my burner does not materially differ from the ordinaryvapor-burner.

In order to produce a heating ame with the burning vapor I iirst secureto the generator-tube I), a short distance below the name, a small dishor outwardly-projecting ange, c, and above this dish I place a largedish, F, which I call a heatintensilien rlhe dish F is hereinrepresented as having six sides, i; but the number of sides is notmaterial, one side serving the same purpose, as will be hereinafterdescribed. In the center of the bottom g of this dish is a hole, h, sothat the dish can be slipped down over the upper end of the burner andrest in the small dish e.

When thus placed the holes in the generator through which the vaporissues to be burned should be a little above the bottom g `of the dish.The sides of the dish stand upward at almost a right angle, as shown,so` that the iiame of the burning vapor will strike in the angle formedby the junction ofthe bottom and sides, and be deflected upward andspread to each side at the same time.

In order to produce the proper effect the distance between the holesthrough which the vapor issues and the upward-projecting sides fi shouldbe regulated according to the size of the opening through which thevapor issues. Two holes, opposite each other, are then suflicient totill the pan with a blue flame of great intensity.

Great care must be taken in order to have the sides i stand at theproper angle, as a little too much inclination outward, or a nearervertical position than the proper one, will destroy the effect intendedto be gained.

When the gasoline is turned on a small portion will run down the outsideot' the gener ator through the hole in the center of the bottom of thedish F and be caughtin the small dish c, and, when ignited, will producea flame below the dish F, which will spread beneath its bottom, and heatit to such an ex` tent as to greatly facilitate the burning of the vaporinside of the dish.

A netting of bars may be laid across the dish F to hold the vessel forcooking, so that there may be a draft from the air-holes a: in thebottom toward the top.

Should the holes through which the vapor issues become clogged, it willonly be necessary to remove the dish F, when the holes can In witnesswhereof I have hereunto set my hand and seal. v
